Which type of sensory receptors are responsible for temperature sensation?

Thermoreceptors are specialized sensory receptors specifically designed to detect changes in temperature. They are located in the skin and other tissues, and they respond to both hot and cold stimuli. When temperature changes occur, thermoreceptors send signals to the brain, allowing us to perceive sensations such as warmth or cold.

This capability is essential for maintaining homeostasis and protection against extreme temperatures, which could be harmful. Understanding the function of thermoreceptors helps clarify their distinct role compared to other types of sensory receptors, each of which serves a different sensory function. For instance, nociceptors are responsible for detecting pain, photoreceptors are involved in vision by sensing light, and mechanoreceptors respond to mechanical pressure or distortion. This delineation reinforces why thermoreceptors are specifically identified for temperature sensation.
